Holding Size with Tight Tolerances

摘要

Tolerances of less than 25 microns can be challenging to achieve and hold. Here are some suggestions for holding them for multiple workpieces. CNC machines produce very accurate workpieces, and they do so repeatedly for two or even 2,000 workpieces. Dimensional tolerances between ±0.002 and 0.005 inch (50 to 127 microns) are easy to achieve initially and hold throughout a cutting tool's life.
